Parrish and Heimbecker was begun in 1909 by William Parrish and Norman G. Heimbecker. Until 1918, the firm bought and sold grain on the Winnipeg Grain Exchange, but did not operate grain elevators.

In 1918, P&H bought ten elevators from Louis Strong and Frederick Dowler, who were Calgary grain brokers. By 1920, P&H had 20 elevators.

In 2011, P&H had approximately 32 grain elevators in Canada, including twelve grain elevators in Ontario, that handle a variety of Canadian agricultural products such as wheat, corn, barley, soybeans, oats, distillers grains, IP soybeans and navy beans.

In the 1980s P&H bought out the bankrupt Soo River Company. They maintained a fleet of ships until they were sold to Canada Steamship Lines. P&H named most of their ships after trees, like Mapleglen. CSL now uses those names.

In 2019, P&H purchased ten grain elevators from Louis Dreyfus Company Canada ULC.
